This volume presents the proceedings of workshops on stable homotopy
theory and on unstable homotopy theory held at The Field Institute as
part of the homotopy programme for the year 1996. The papers in the
volume describe research in the subject, and all included works were
refereed. Rather than being a summary of work to be published elsewhere,
each paper is the source for the new material it contains. The book
presents open problems with directions for future research.
